Flambards in Cornwall has recently invested in a energy regulating device,  from this they are now able to run there attractions with 218 volts instead of 242. This minor decrease has saved them a whopping £11,000 in just 6 months with 'Voltis Units' which they expect to have paid for itself in 3 years. From the Southern Park using this device it has proven that a machine controlling energy levels very precisely can be of huge benefit, especially in such an energy-consuming area. With such a proven benefit both financially and environmentally, it would be surprising not to see any other parks purchaser there own device or those which would do the same function. It would be presumed that one for bigger parks would save much more money and therefore pay for themselves even quicker. http://www.bbc.co.uk/news/uk-england-cornwall-11040059
